Specification of Letters Patent.

Patented Oct. 18, 1921.

Application filed November 5, 1919. Serial No. 335,975.

To all 10 7mm it may concern:

Be it known that I, LE ROY G. CLARK, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain newand useful Improvements in Electroliers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to electroliers of the type in which a single lamp is used.

The principal object of the invention is to provide a collapsible structure which will permit repairs and alterations to be made without disturbing the wiring.

Another object is to provide a construction which will save space in shipment or in storage, and which will comprise materials not liable to breakage. v

A further object is to arrange the various elements to screen direct light from the eyes while permitting all the reflected light to be utilized.

Additional objects will appear as the structure is described in detail.

In the drawings Figure 1 is an elevation of a preferred embodiment of my invention, parts being broken away,

Fig. 2 is an elevation with the structure closed ready for shipment or for repairing, parts being broken away;

Fig. 3 is a fragmentary view showing the relation of the framework to the supporting member;

Fig. 4 is a vertical section of the lower portion of the supporting member and of the elements of the framework which are secured thereto; and

Figs. 5 to 12 inclusive are views of details.

The main cover 1 is made of silk or of any other suit-able flexible material which may be readily-folded when the structure is collapsed. Beneath the main cover is suspended a refractor 2, which may be of silk or of translucent glass of the common type, acting as a shield to protect the eyes from the glare of the lamp. Arranged above the cover 1, is a tassel 3 of silk or other suitable material which may be spread out, as shown in Fig. 2, when the structure is folded, to serve as an ornamental top for the closed cover. Around the lower edge of the cover 1 is secured a cord which passes through eyelets 4 in the lower ends of the ribs which support the cover. The fabric of the cover is secured to this cord which forms the lower edge of the frame work, and a fringe 5, also secured to the cord serves as a decorative feature.

A tubular conduit 20 for the electric wiring acts as the main supporting member, by which the entire structure is suspended from the ceiling. The lower end of this tube 20 is screw threaded at 21 to receive the ordinary lamp socket 22 which acts as an abutment to prevent downward movement of the disk 13 from which extend the chains or other supports for the refractor 2. Immediately above this disk 13 upon the tubular conduit 20, is a screw-threaded sleeve 14. Mounted upon this sleeve are three disks which are held from vertical movement upward by a thumb nut 11 which engages the upper portion of the sleeve 1 1 when the parts are in the closed position. The intermediate disk 6 has a series of perforations engaged by the ends of brace arms 16, the other ends of which are pivoted upon lugs 7 upon the ribs 12. Upon the upper face of the disk 6 is a shoulder or collar 9 which acts as a spacing member to prevent the brace arms 16 from binding by contact with the upper disk 10. This upper disk or plate 10 is of a size to cover the opening in the frame work or collar 17 at the upper end of the cover 1 to keep lights and shadows from the ceiling. This framework 17 is connected by radial members 19 with a disk 8 which lies between the disk 6 and the disk .13. The framework 17, ribs 12 and the cord 18 connecting the lower ends of the ribs form the supporting framework to which is secured the silk or other fabric which serves as the reflector for the lamp 23.

The conduit 20 has an ornamental casing 15 at the lower end of which is secured the tassel 3. By varying the fabrics to suit the decorations of the room, many diiferent effects may be produced without buying a new dome or disturbing the wiring.

lVhilc I have described the members 6, S, and 13 as disks and have illustrated them as flat members with perforations, it will of course be obvious that supporting members of other shapes and having other attaching portions might be substituted therefor, though I deem the disks to be the simplest and most convenient form of securing means.

Many other changes may be made in the various details of my structure, and the principles of my invention may be applied to devices varying widely in design from that herein shown. Similar collapsible frameworks may readily be adapted'for use with wallbrackets or applied to lamps mounted upon a stand. 7

I do not wish therefore, to be'limited to the exact size, shape, form, proportion, or details of structure herein illustrated, except as may be necessitated by the terms of my claims when broadly construed.

I claim:

1. An electrolier comprising a supporting member having a screw-threaded lower end, a lamp socket engaging the screw-threaded end of the member, a disk upon the supporting member above the lamp socket and acting as a support for a refractor mounted below the lamp socket, a screw thread-ed sleeve on the supporting member, a disk carrying a collar and a disk having braces pivoted thereto both mounted on the sleeve, and a lock nut engaging the upper portion of the sleeve to hold the disks in position on the sleeve, a series of ribs pivoted upon the collar,the ribs also having pivotal connection with the ends of the braces, and a cover supported by the ribs.

2. An electrolier comprising a supporting member, a lamp socket secured to the lower end of-the member, a disk held in position upon the supporting member by the lamp socket, a refractor carried by the disk, a second disk mounted upon the supporting member and carrying a collar, and a reflector carried by the collar.

3. A structure as in claim 3, in which there is a flexible element connecting the ends of the ribs remote from their pivotal connection with the collar.

4. An electrolier comprising a supporting member, a collar carried by the member and having a series of ribs each'pivotally mounted at one end on the collar, a disk vertically movable upon the supporting member to a position above the collar, braces pivoted at one end to the disk and at the other end to the central portion of the ribs, the arrangement being such that theribs extend outwardly when the disk is" in its lowermost position, and means for holding. the disk in adjusted position.

5. An electrolier having a supporting member, a lamp socket secured to the lower end of the member, a disk mounted above the lamp socket and carrying a refractor beneath the lamp socket, a second disk carried by the supporting member above the first disk and having a collar spaced. therefrom, a series of ribscarried by the collar and mounted for pivotal movement, a third disk carried by the supporting memberabove the second disk and having a series of braces carried thereby, one end of each of the braces being pivoted to the'disk and the other end to a rib, a fourth disk spaced above the third disk and adapted'to enter the upper end of the collar to form a closure therefor, the third and fourth disks being vertically movable upon the supporting member to permit the collapsing of the ribs downward, and a flexible cover carried by the ribs.

6. An electrolier comprising a supporting member, arefractor carried at the lower end of the supporting member, a collar mounted upon the supporting member and having a series of ribs each pivotally secured at one end to the collar and pivoted between its ends to one end of one of a corresponding series of braces, a disk to which the other end of each of the braces is pivoted and which is verticallyslidable upon the supporting means, and means to secure the disk upon the supporting member at a point in whioh the ribs are held in an extended position, and a cover of flexible material carried by the ribs.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

LE ROY G. CLARK.
